I’m watching the numbers daily especially for Central Florida and the curve seems to be holding here for now with the distancing measures in place. Osceola County has a face mask in public order starting on Monday. Please take these measures seriously. My wife is an ICU nurse with her floor dedicated to positive patients.

That data is not hard
It is
Trends and tendencies
With the latency in contracting then testing, verification then reporting it is "Last Week's News"
For your own safety treat everything outside the walls of your dwelling as if it is a hot zone.

Virus versus masks
Extraordinary complex subject
The virus is elliptical shaped with a max dimension of 15 microns. The primary function of an untreated mask is to muffle projectile exhalation like coughing or sneezing.
This info is taken from a John's Hopkins white paper.
Note a Hepa 2 filter is commonly rated at 1-2 microns

CPAP machines have two filters
One is foam to filter gross particulates
An inner one white in color is HEPA 2 grade which will block 100%;virus.

Hi,
The size appears to be about 70–90 nanometers or 0.07 to 0.09 microns.

Not what we were told about the white HEPA,at most 60-70% from the sleep study place and her lung doctor. But any filtration is better than nothing.

CPAP filters filter incoming air. If the machine has a HEPA filter it should protect the person wearing the CPAP mask from SARS-CoV2.
HEPA filter vs SARS-CoV2
Problem with CPAP is that it is extremely dangerous for anyone in the area if the person wearing the CPAP mask has COVID 19 because the CPAP outlet is not filtered and the virus in the outlet air can be aerosolized, meaning that it can linger in the air for a long time. EMS personnel have been directed to avoid using CPAP with suspected COVID 19 patients. This is also the reason why hospitals generally have been skipping CPAP, BiPAP, and high flow O2 through Non-Rebreather Masks and going straight to vents. Vents protect healthcare workers by eliminating the possiblity of aerosolizing the virus.
COVID 19 CPAP Use
EMS COVID 19 Airway Management
It is believed that an aerosolized SARS-CoV2 can remain in the air for hours and can travel far more than 6 feet but experts still believe the primary transmission method for COVID 19 is through droplets which don't travel more than about 6 feet. However, it is known that the virus can be aerosolized during certain medical procedures including administration of O2 through non-rebreathers, CPAP/BiPAP, administration of nebulized medications, and during intubation. This is what makes it so dangerous for first responders and other healthcare workers. Investigations continue into the likelihood of aerosolized SARS-CoV2 in non healthcare scenarios.
SARS-CoV2 spread through droplets can be fairly easily controlled with proper measures. Aerosolized SARS-CoV2 is truly scary. My personal opinion is that the worst cases of COVID 19 are those that result from an exposure to aerosolized SARS-CoV2 and exposure to droplets probably results in less severe cases unless the patient has comorbidities. But that is just my opinion.

Defining it down to a point or two the above is correct except for the sleep study comments. HEPA is HEPA and is not open to negotiation. The filters are either HEPA certified or they aren't.
Specialized medical doctors are worthy of their title. MDs are not specialists. If you have sophisticated questions refer them to a specialist. I like Internal Medicine doctors because of their wide range of training and experience
Follow your MDs advice until a specialist over rides it.
I stated that a CPAP filters incoming air for the CPAP patient. The next thing I see is that the patient is infected and the air in the room has been infected.
